Properties:
Name Type Attributes Default Description
options.toggle Boolean <optional>
true

If true, the button is toggled on click.

options.press Integer <optional>
0

Controls press behavior. If options.toggle is false and this option is 0, the toggle button will toggle until released. If options.toggle is true and this option is a positive integer, it is interpreted as a milliseconds timeout. When pressing a button longer than this timeout, it will be toggled until released, otherwise it will be toggled permanently.

options.delay Integer <optional>
0

Delay all actions for n milliseconds. While actions are delayed, the widget has class .aux-delayed. Use to force users to press the button for a certain amount of time before it actually gets toggled.

options.icon_active String | Boolean <optional>
false

An optional icon which is only displayed when the button toggle state is true. Please note that this option only works if icon is also set.

options.label_active String | Boolean <optional>
false

An optional label which is only displayed when the button toggle state is true. Please note that this option only works if label is also set.

A toggle button. The toggle button can either be pressed (which means that it will switch its state as long as it is pressed) or toggled permanently. Its behavior is controlled by the two options press and toggle.
